This invention-relates: to sp ring seat atin-orderto prevent relativerotationof the 'tachments, and is more particularly directed to a, spring means adapted to be attached between the pole of '5 mounted thereon.

VAn object of this 1 v a tractor v and the seat nvention is to rovide an attachment for-attaching seats" to the poles of tractor seats which is adapted "to be attached to the pole of any tractor andto the seat customarily carried thereby Q and'which provides means for taking up the shocks in any direction.

Another objectiof inven tion is to pro- Vide an'attachment for securing seats to the poleo'f a tractor which i'siot inexpensive construction, including no wearing parts and which provldes adjustment' means permltting ' or similar'fidevic e upon w customarily secured. j The-pole 1,1's, cordance with modern constructions,
